The power applied to VDD (as well as VSS, if not grounded)  
should be well regulated and low noise. Switching power  
supplies and DC/DC converters will often have high-fre-  
quency glitches or spikes riding on the output voltage. In  
addition, digital components can create similar high-fre-  
quency spikes as their internal logic switches states. This  
noise can easily couple into the DAC output voltage through  
various paths between the power connections and analog  
output.  
LAYOUT  
A precision analog component requires careful layout, ad-  
equate bypassing, and clean, well-regulated power supplies.  
As the DAC7615 offers single-supply operation, it will often  
be used in close proximity with digital logic, microcontrollers,  
microprocessors, and digital signal processors. The more  
digital logic present in the design and the higher the switch-  
ing speed, the more difficult it will be to achieve good  
performance from the converter.  
As with the GND connection, VDD should be connected to  
a +5V power supply plane or trace that is separate from the  
connection for digital logic until they are connected at the  
power entry point. In addition, the 1µF to 10µF and 0.1µF  
capacitors shown in Figure 4 are strongly recommended. In  
some situations, additional bypassing may be required, such  
as a 100µF electrolytic capacitor or even a “Pi” filter made  
up of inductors and capacitors—all designed to essentially  
lowpass filter the +5V supply, removing the high frequency  
noise (see Figure 4).  
Because the DAC7615 has a single ground pin, all return  
currents, including digital and analog return currents, must  
flow through the GND pin. Ideally, GND would be con-  
nected directly to an analog ground plane. This plane would  
be separate from the ground connection for the digital  
components until they were connected at the power entry  
point of the system (see Figure 4).
